From the incident of incompatible grease fitting thread last year, I would like to request actions from your team as below for 2015 valve greasing campaign.
Please coordinate with your team before the job start krub.
· Ensure that all threads of grease fitting are re-tightened after greasing activity, especially when the fitting is replaced.
· Some valve has connector, installed to valve body before the grease fitting, as shown in the picture below.
In this case, please also re-check thread type of connector (NPT or NPSM) before re-tighten or fitting replacement.
If the grease fitting is replaced, inserted check valve inside the connector must be re-tightened before install the grease fitting.
· During valve greasing campaign, please provide daily report, including pictures, in order to let PTTEP verify correctness of the job in due time.
You don’t have to make an full / official daily report.
I just need to see the list of valve greasing on each day, with pictures before & after greasing or fitting replacement.
If you need any further clarification, please feel free to contact me.
Thank you.
